Problems solved by technology

At present, the most commonly used photovoltaic power plant pipe pile foundations in the market are high-strength prestressed pipe pile foundations and steel screw pile foundations. Among them, high-strength prestressed pipe pile foundations have the advantage of good construction flexibility, but they have the disadvantage of concrete pouring and tamping. It is not dense and easy to crack, which leads to the problem of poor pile quality. The steel screw pile foundation has the advantages of light weight and convenient construction. However, the steel screw pile foundation has the problems of high cost and low bearing capacity. Therefore, it is necessary to develop a A concrete pipe pile with good crack resistance and good pile quality

Abstract

The invention discloses an anti-crack cement pipe pile for photovoltaics and a preparation method thereof. The anti-crack cement pipe pile comprises the following components: aggregate, cement, admixture, admixture, anti-crack component and water. The preparation method of the cement pipe pile is as follows: take the aggregate and the admixture, stir, and mix to obtain the first mixture; weigh the cement and the admixture, add water, stir, and mix to obtain the second mixture; The first mixture is added to the second mixture, stirred and mixed to obtain concrete; the concrete is placed in a mold, stretched, and centrifugally formed to obtain a semi-finished concrete pipe pile; the semi-finished concrete pipe pile is cured, demoulded, and naturally cured , to obtain the finished concrete pipe pile; the experimental results show that the prepared concrete pipe pile has excellent crack resistance.

Description

technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a crack-resistant cement pipe pile for photovoltaics and a preparation method thereof. Background technique [0002] In recent years, the photovoltaic industry has developed rapidly. So far, my country's total installed photovoltaic capacity has exceeded 100GW. According to the development plan of my country's photovoltaic industry, it will still maintain a relatively rapid development speed in the future. The largest proportion of civil engineering in photovoltaic projects is photovoltaic support and foundation engineering. Common photovoltaic support foundations include reinforced concrete independent foundations, strip foundations, micro-cast-in-situ pile foundations, high-strength prestressed pipe pile foundations, and steel screw pile foundations. etc. At present, the most commonly used pile foundations for photovoltaic power stations in the market are high-strength p...
